Braking

A reasonable length of time ago I started to learn how to teach mathematics the year was 1995/6. During that academic year I received my second placement at a school in Kingston Upon Thames. I was living in Ealing at the time and my first school was The Featherstone High School in Southall and it was a couple of stops away by train. However, to get from Ealing to Kingston was not the easiest of journeys and meant about an hour on public transport. So, I decided to get a motorbike. That teacher training year was a surprise to me for two main reasons:

I discovered that I really loved teaching and decided to stay in that profession. My plans up to then had been to join the RAF as an educational officer.
I bought a motorbike, which I consider instant death traps, and I loved it.

So, I took my motorbike test in 1996 I think. I couldn’t remember the braking distances for different speeds and so one of my my flatmates, Greg, came up with the formula:

Braking distances formula where x is speed in MPH and result is braking distance in feet

Using this formula gives you the braking distance in feet when x is in miles per hour. Effectively it splits into two parts; the x is the thinking distance which is roughly one foot for each mile per hour and the x^2 is essentially the kinetic energy factor. I actually used this formula to work out the answer to the question in my motorbike driving test and got it correct although the tester was somewhat surprised I was using feet rather than metres even though both were acceptable in those days.

This distance is an estimate and cars nowadays will be able to stop in much shorter distances. The more you pay for your car the shorter the distance to stop [ish]]. Basically it’s one hundred metres to stop from 70 mph. That’s quite a distance and would probably surprise most people to see it laid out. It’s the length of a running track straight. When I try to visualise distances in the hundreds of metres I visualise a running track opening out to a straight line and then going across the school field. Humans are generally rubbish at estimating distances because it’s not something we do that often. Distance estimation is important in application of fire when shooting and you need to estimate distances quickly using visual clues to make sure you aim at the correct stop to hit the target. Bullets fall down to Earth, accelerating at 1g.

Now we get to the main point of this communication. In my experience over the last two months people are either:

Stupid
Unable to estimate distances
Unable to understand risk
Unable to follow instructions
Think they are indestructible

None of those things is mutually exclusive so maybe it’s all of them. My evidence is purely anecdotal and comes from my experiences of going to the supermarket. I have been to work thrice since the UK lockdown started and the few people there have been good at keeping their distances. My place of work is still open to the children of key workers and there have been some in allowing sections of this country to still function. The only other place I have mixed with the public is at the supermarket. I haven’t really ever had food shopping delivered and decided I wouldn’t start now and take a slot from someone else who needed it. Going to the supermarket is something I normally enjoy. I don’t know why but I like seeing the shop. If you think that is strange then I really love supermarkets abroad, I think they are such an insight into the people and I will happily walk up and down every aisle to see what’s there.

My normal supermarket is a Sainsbury’s nearby. In fact I’ve been using them for a while since my Nectar points balance went negative due to their errors. I’m not sure of the economic implications of a negative Nectar balance but I decided to shop there for a while. The first time I went to the supermarket they had set up a queuing system with lines on the floor where people could stand. I am not convinced these lines are two metres apart because two metres is probably further than you think but they are apart and so I’m not going there to measure them. That first time queuing someone was chatting to the person behind me and had to be asked to move away. I mean, I thought the instructions were pretty clear. Two metres is two metres. It’s more than the height of a standard house door. If you stand there with your arms outstretched you shouldn’t be able to tough another person’s hands with their arms outstretched.

Inside the store my experience was mostly positive. People seemed to be mostly keeping their distance. Most aisles are around two metres in width and so if you go down the sides you are probably a good distance away. I did find that some people weren’t following the instructions and while I waited at “pinch points” other people would go between me and the person I was waiting for. This, I think, is mostly to do with people not having patience or any altruism. I tried to do the right thing by keeping my distance but some people weren’t doing their best. This was a little frustrating. Mostly I found the experience OK and I don’t think I was too worried by the other shoppers, by and large it was OK.

A few weeks into the lockdown in the UK I went to a local Tesco store because I needed to buy some clothes. The Tesco has a larger selection of clothing and I honestly didn’t want to go to the Asda at the top of the hill because I was being snobbish. The queuing system outside the Tesco worked well but once inside I found there were problems. Tesco have placed arrows on the floor to try and make their customers move in the same direction and allow more people to browse particular products. That seems perfectly sensible but when a good proportion of the customers decided NOT to follow the one way system – WHICH IS THERE FOR THEIR SAFETY AND HEALTH – then the system fails. I was a good boy and followed the rules in place. That evening I found that a lot of customers either didn’t see the arrows or just ignored them. Too many people passed too close to me. My observances are:

People wearing face masks and gloves seem more likely to pass close.
Younger adults don’t give a shit.
Tesco don’t enforce the system – but how could they?
Kids don’t know better so that’s fine – don’t take kids shopping unless your situation requires it.

I hated the time I spent in this supermarket. It was frustrating and increased my stress levels to very high. I just wanted to get my stuff and get out. I really don’t understand why people won’t follow guidelines in place to keep them safe. I’m pretty sure they haven’t understood the risk assessment of these activities. Let’s look at these problems I saw:

Face masks and gloves – the evidence is that face masks don’t protect you from the virus. What face masks do is reduce the chance of you passing on the virus if you have it. Now, if you have symptoms you shouldn’t be outside at all. But, you could be asymptomatic, or you could be at the infectious stage just before you get symptoms. Wearing a face mask gives you a false sense of security and so you put yourself into more risky situations. I saw this is Tesco, I saw people wearing rushing around and getting close to people and they were the ones wearing face masks. Gloves won’t do shit. Gloves, again, give you a false sense of security and make it more likely that you will touch stuff. The best thing you can do is wash your hands before you go out and then wash your hands as soon as you get back. Do your best to not touch your face in the times inbetween.

Younger people – they have that sense of invulnerability that I once felt and I get it. They are going to do the things they want to do. But it could be that they are a massive vector for the virus because they are more likely to be asymptomatic. In a recent exercise walk around a lake I saw a group of around twenty youths all together. I understand and no one is really going to be able to tell them what to do.

Tesco decided to implement a one way system. I have spent a while thinking about this and my stress levels at Sainsbury’s are less because they don’t have a one way system. Therefore there isn’t a system for people to follow and so I don’t get annoyed when they don’t follow it. I still get annoyed by people passing too close but there isn’t the added issue of those people also blatantly ignoring the safety arrows of directionality.

I haven’t seen many young kids when I’ve been out and about. I understand that there are family situations that would make it hard for people to leave kids at home and I am sympathetic to them. You can only tell youngsters to do so much. This, of all the transgressions, seems the one that’s OK.

I go to Tesco rarely. This is to minimise my annoyance at people not following the system. I don’t wear a mask and I don’t wear gloves. In my head I model the water suspended droplets flowing around people as they move around and I try to avoid those areas. I hold my breath at certain times and I try to minimise the risk to myself. I don’t know if I’ve had the disease and I don’t know if I would be immune. I hope I have had it. I would like to be in the position to know that I don’t have to worry about getting it. I would like to be able to do my work and help others knowing it is unlikely I can pass it on and also unlikely I can catch it again. These are all things I do not know. The most important thing for people to do now is to reduce their own risk of getting the disease or passing it on. Until there is a vaccine available everyone is likely to get this at some point. Everyone is going to get ill and there are going to me many more deaths. What we need to do is minimise the risks to all and keep the health services going by spreading out the infection rate.

A couple more things to mention; the virus is called SARS-CoV-2, that’s the official name, the disease you get from the virus is called COVID-19. The virus belongs to the common cold virus family and not the flu virus family – they are very different shapes. The R value that the media are going on about is really the R₀ value. That’s pronounced R Nought or R Zero. I think the media have been a little lazy on this one but that could be just me. There are other R values and it’s important to talk about the one you mean. This one is the only one being talked about in the media so maybe I should be softer on this issue.

Seasons In The Abyss – Slayer

It’s been too long since I last wrote a review on this topic, I’d actually forgotten I had done some of the “S” albums. To have Seasons In The Abyss as a resumption of service is great. This album is absolutely fantastic. It’s hard, heavy, powerful and will smash you apart. I’m not a megafan of Slayer I have seen them twice I think and I enjoyed the shows. They are one of the big four and so deserve their place in history. Every now and then the music of Slayer is a requirement because it’s just right. Make no mistake this is thrash metal and a perfect example.

War Ensemble – fast, powerful, lasting lyrics, what’s not to like? I remember Slayer at the Clash Of The Titans concert in Wembley arena announcing that they were going to record the music video to this song and were going to play along to a backing track – that did not go down well with the crowd – so they played it live.

Expendable Youth – Very good song. I do like some heavy cymbal use.

Dead Skin Mask – creepy and scary. This song messed me up the first time I heard it. I bought this album on music cassette [tape] and was playing it while walking from the record shop. Towards the end of this song a girl’s voice comes on asking for help. I hadn’t realised it was part of the song and thought it was someone behind me asking. Pooped myself.

Hallowed Point – see below lyrics, need I say more?

High velocity bullet at close range
Can damage the mind
Shattering the skull shredding the brain
Severing the spine
Slayer – Hallowed Point

Seasons In The Abyss – a tour-de-force of a song. Absolutely amazing. Calming, heavy, spooky. All of that.

I know I haven’t written about every song and there are times when I do. I think the biggest endorsement I can give this album is that I don’t skip any of the songs and love the whole thing. It’s a well rounded collection of songs.

CV-19 UK Tour

I’m missing seeing other parts of the world. I’m currently stuck in a small triangle within Kent and while I do appreciate the luck I have in being in this area I am also bored of it. I would like to visit RAF bases, I want to see other people and I would like to be atop mountains. Normally by now I would have been to the Lake District and also we had plans to go to RAF Halton, RAF Brize Norton and RAF Wittering. I miss those things and as much as I know I sometimes struggle socially I do miss the people.

So, I’ve started playing X-Plane about 30% seriously. I’ve been learning how to use navigation equipment within the aircraft and I’ve even started playing with the radio settings but my last attempt at that failed and I got told off by the game for not following the ATC instructions! I recently got some payware in the form of an aircraft model, the T-7A, and it’s a nice plane. It flies easy enough, can get up to speed quickly and has a glass cockpit. I’ve even figured out some small parts of the autopilot.

It’s slightly frustrating having to move my view around from the HUD to other parts of the cockpit to see the instruments and I’ll have to think about how to make that easier and quicker – maybe I need a second monitor? – but I’ll cope for now. One of the things I’ve always struggled with first person shoot em ups is that quick glances never seem to be that and moving the view can be time vital. Also, I’m not very good at them.

I’ve been flying around the country as part of this summer’s tour. The first few flights were down in the south over Kent and Cornwall but now I’m heading around airport hopping. A rough idea of places been so far are: RNAS Culdrose, Llanbedhr, RAF Valley, BAe Warton, RAF Leeming, Leuchars, RAF Lossiemouth, Kirkwall, Shetland, Stornoway, Prestwick, Glasgow, Isle Of Man, Belfast, Barrow.

This has been good fun so far. I think I’m going to head down the east coast next. Let’s see where I end up!

May 24 2020May 24 2020

Normal

I’ve been concerned recently with my lack of emotion and terror at the current Covid-19 and lockdown situation. Even when this started and I self-isolated on 17 March 2020 I was very much “oh well, I’ll have to do that” rather than feeling any particular angst at the need to do that. The last two months have had me working pretty hard remotely and only seeing one particular triangle of Kent. I’ve been to work, the supermarket and dropped the kids off. That is all I’ve done. I’ve not been anywhere else and it seems to feel completely normal. The economy is screwed, people are dying and risk-management has never been more complex and I’m just OK – I’ll get on with it.

I don’t know if this is a particularly British response to things. We seem to be a nation of people who by and large do as they’re told. That’s why we haven’t had political revolution in this country for four hundred years. It’s why, after the first world war, we didn’t have a massive change in society and leadership along with the rest of Europe. It’s probably why we tend to think we are better than everyone else. So, if the government tell us to do something by and large we do it. Sure, there are some groups who don’t understand or don’t care but this country has largely stopped for two months.

We like to think that those in charge are capable of being in charge. It is clear to me that this current government is a far from capable as possible. We would have to go back quite a way before I thought we had a government that actually cared. Those leaders at the top are lying, racist wankers. They have no talents. The people get the government they deserve. If you voted for these scum then you are to blame for the utter lack of planning, caring, organisation and intelligence in leadership at the moment. This makes it even more bothersome that I’m rather calm at the moment.

I do wonder if there is only so much panic and worry the human person can cope with. Eventually that all becomes tiresome and something has to give. It could be your mental health and the panic doesn’t die but other aspects of human behaviour and thought get amplified. This is not a good place to be. I feel that my behaviour has been more of a “oh well, let’s just get on with it” attitude. But not because the government tells me to, but more of a – this is the situation now and so I should do my best to be within that system. I guess I am being that “get on with it” British person. I know the risks to me are quite slim. I know there’s a decent chance I’ll come out of this fine. I am also glad I have a state income at the moment and if that fails then there are much larger problems with society and a lack of money is not going to matter.

I guess humans [extrapolating from n=1 : me] seem to adjust to change quite well and will do as they are told. I will say once again that I do not trust a single word of advice from the government but I also understand risk, biology and mathematics to a certain degree and so am able to understand what to do. I occasionally imagine what it would have been like eighty years ago. In the skies above my village there would have been bombers, fighters and all hell breaking loose. People living in my house at that time might have struggled mentally and might have gone mad, we don’t have those stories. But, those people living in my two up two down might have gone about their daily business thinking that this is what life is like at the moment and we still need to get the bread.

I do have a constant sense of anger at the government and the lies they say along with how terrible they are. The older I get the more I see the inequality and the uselessness of those in charge. I’m not sure I have ever really been so impressed with a government looking back through my time. We’ve had the following prime ministers Callahan, Thatcher, Major, Blair, Brown, Cameron, May and now Johnson. Of those that I remember I think two of them might have been just about OK and did the best they could. I am not endorsing everything they did – illegal wars for one thing and PPI for another – I’m just saying they were less bad than the others. There is far too much that needs to be done and too few people who really see the need. I said to a manager of mine recently that I’m always angry. I am. I’m like Dr Banner but without the green alter ego.

Safe

There is nothing that is safe from risk of injury or harm. Just living day to day carries a risk of death. You could drop down now from a heart attack or already have cancer. Some illness is random and terrible when it happens and although we know there are things to do to reduce the risk that is all you can do, reduce the risk. Safe really means that the risk of bad stuff is reduced enough for us to accept what we are about to do. Humans are terrible at understanding risk.

Every time we do something then we are accepting the risks associated with that action for the reward. If I go to the supermarket in normal times then I would drive there, I would come into close contact with a lot of other people and I would then drive home. Driving contains the largest risk there but I accept the risk for the convenience of getting to and from the supermarket easily. Danger of disease transmission isn’t something that normally enters our heads but being in a closed building with a few other hundred people who have touched all manner of surfaces with their dirty hands could prove to be risky behaviour if one of them had a dodgy disease [again, talking in normal times].

If I want to get on a train to somewhere then I hope that it won’t crash. That’s not a thought that goes through my head because generally train journeys in this country are quite safe. The risk of bad things happening is low and the reward is good – I get somewhere fast and normally quite relaxed. Flying is another one of those activities where we accept that the risk of death is acceptable for the convenience of travelling somewhere fast and far. We know that aircraft are safer than using the roads but we are more worried about flying because humans are terrible at understanding risk. 267 people died in passenger planes last year WORLDWIDE compared to 1870 killed on UK roads in the same time period.

I did a zip-line-wire-death-slide thing in Cornwall over a quarry lake. Was I worried about doing that? No. The risk was low. I was strapped in. It was run by a reputable company and I assumed that they had met all safety aspects of the set up. While some might worry about it and hopefully overcome their fears, those fears are unfounded. The risks have been reduced to a point where they are acceptable for the outcome. The zip-line was great fun. Last summer I had a flight in an RAF training helicopter. Now, ‘copters are the worst of transport methods for technical difficulties and flying characteristics. Was I worried? No. The risks were acceptable and it was great. The processes behind the RAF are exceptional and the risk was suitably low. I once had a flight over the 12 Apostles in Australia in a R44 [I think], again, the risks were low and I was trusting the regulations that existed for that country.

If we chose to do something then we should be balancing out the risks realistically with the rewards. We trust the regulations. We hope that when things do go wrong that the regulations change to take that into account. We trust that there are organisations out there making sure these things are done properly. This does contradict capitalism a little as companies will moan about “costs” but they get over it and their product gets the boost. There was a time that companies had to be told to include seatbelts in cars. It became law for three-point harnesses to be included in the front seats in 1968. The law to wear them was introduced many times in the 70s but failed [how the fuck?] and wearing front seatbelts eventually became compulsory in 1983. Rear seatbelts became compulsory equipment in 1986 and mandatory to wear from 1991. I mean, how did it take so long? What was the problem? Why are people so stupid?

I’m a qualified shooting range officer and I can tell you that the regulations are immense. The rules are all designed to make the activity as safe as possible. Is all risk removed? No. But the risk is manageable and acceptable. The most likely injury is a small cut to your hand where you are dealing with metal parts on a weapon, but even this is a small risk. I even take teenagers to a shooting range. It is safe. The regulations and environment are built and designed in such a way that the risk of injury or worse is reduced.

If the risks are mitigated through planning and regulation then activities are deemed acceptable. We spend our entire lives running mini-risk assessments in our heads all the time. I’m extrapolating from n=1 there, me. We think about the reality of risks although some people are overcome by the perception of risk and fail to complete some activities. When we talk about something being safe we really mean that the risks are reduced for us. The reward is worth it.

Laying Around

The village in which I live was primarily built for workers of the Burham Brick Lime and Cement Works Company based close by at the river front. The entire landscape around here was formed by the mining for materials. The brick works supplied bricks until around 1938 and the product was used for the building of the East Wing of Buckingham Palace. I’ve heard that the bricks in my house are the same type as those in the domain of the privileged.

If you wander around down near the reservoir and the river you will invariably see bricks lying around. This one below I took out of the ground out of sheer curiosity. It’s quite nice that these are just there for all to see.

UK Scenes

So, along with getting the new PC was the general concept that I would have a machine capable of running X-Plane which has ridiculous graphics simulation algorithms. I’m sure there could be flight simulators that run quicker and also look better but because of the physics engine employed by X-Plane it is the most accurate in terms of aircraft movement through the air. It used to be that to run X-Plane I had to turn off any clouds. These seem to really mess with the frame rate and the bottleneck occurs on the bus between the CPU RAM. I had spent a lot of time reading about finely tuning the software to give the best compromise between frame rate and looks. The new PC doesn’t really seem to have any problems and I just turn everything up to 11.

Browsing for a slightly better looking Great Britain I found, I don’t remember how, a website offering sexy GB scenery. I had to pay for it but it did look good. I was concerned about splashing out without being able to test the software but the company had a Demo area around Southampton. Orbx have a selection of payware airports along with GB scenery. I downloaded the Demo area and flew from Southampton Airport over Portsmouth and Gosport. The fact that I could see aircraft carriers in the harbour along with HMS Victory and the forts in the Solent meant I was smitten. The whole area looked great. So, I took the plunge and bought some scenery of GB. I had some cash stashed away from the sale of my old graphics card and those proceeds went to these views.

I have not been disappointed. There is now 367GB of GB scenery on the hard drive and while load times feel like forever, X-Plane is terrible at some things, the whole of the island of Great Britain looks spectacular. I’ve flown from Manston to Lydd to Southend to Heathrow. I’ve also covered Cornwall along with the Lake District. Next steps will be Wales and Scotland, specifically the Mach Loop and Lock Ness. Below is a gallery of some sights so far. After flying for a little while I turned some clouds on just to make it look more realistic. I know I’ve got the frame rate showing up in the top left corner and you might think that 30fps isn’t that great. Trust me, I would have had around 2fps using the old PC and these settings. I’m not really into bragging rights about fps and anything more that 50 seems iffy, not worth it? Happy to be proved wrong on that. Also, below, are a couple of pictures of the F-35B using the old scenery. Hopefully you can see the difference.

The Rig

As I was falling asleep last night I’m pretty sure I was drafting a communication for this site. It was going to be short but worth it. A suitable piece of content that would mean I keep publishing things here. But I forgot what it was. I could have me-mailed a message but I don’t like looking at my phone once I’m upstairs and so I hoped I would remember it. I didn’t. My hope failed.

So, instead, here’s another picture of my PC. I hadn’t realised I’d put something here a short while ago but here it is in flight simulator mode.

I’ve already been criticised for the PC LED colours not matching the rest of the unit, I can change them, I just like the red, it makes it look angry. Also, the keyboard has lights which I’m not convinced are worth it but I smile whenever I look at them whirling around. I could match that too but I don’t care.

On the desk is a Pooley’s Flight Guide to every UK airport which makes taxiing around quite a lot easier. It’s open at Southend EGMC and I’ve been flying a T-7A Red Hawk around over Kent and shooting shit. I’m using the F-7 version because it’s got bang stuff added to it. The plane was made by AOA Simulations and is the third piece of hardware I’ve got from them. I have a F-35B, the CV-22 and this F-7 T-7A. I like their kit. I also like my Grumman Goose but that’s mostly because I’m still in love with Tales Of the Gold Monkey.

It looks like I need to take some pictures of the F-35B and so I will get on that soon. Look out here for more pictures of these lovely planes. I might try and find some extra special spots around the world to bomb also.

For Health

A while back I gave up my Spotify subscription. My reasons were partly that I just kept listening to the same songs over and over and I also thought the payment that the artist receives was paltry. At that time I decided I would buy albums of artists I liked and own the music. I think this is the morally correct thing to do. There are a number of artists I really listen a lot to and they don’t make masses of money. I’m not talking about mega-bands like Metallica or Maiden, I’m talking here about bands I regularly play in 500 seat theatres. I say theatres but they are more the loveliest dives in London.

I saw the band/singer/artist Leaether Strip at M’era Luna a few years ago and I loved it. I thought he was great. Such a nice chap with excellent music. His husband was playing the keyboards for him and it was clear there was such love between the two of them. Now, I’m not really a “meet your heroes” type of person. I’ve heard enough stories about famous people being, well, people and assholes so I’m happy to leave the artists alone and let them get on and I’ll enjoy what they do. Some music I don’t listen to anymore because of the behaviour of the artist – LostProphets.

The reason for this communication is I bought an album by Leaether Strip and I know I like the music but I also know that the money helps the two men get on with their lives and especially to support Kurt as he’s been ill for a while and has had a kidney transplant. I get music I know I will like and they get a little bit of help for their lives. Seems a fair saw to me. I’m very happy for you to use the link in this paragraph to go and buy stuff also.

Megaliths

This area of Kent in which I reside has some decent human history going on. When mostly forested the island of Great Britain [it amuses me immensely that this place is named after a part of France, must make those racists really angry, especially singing Rule Britannia] had many locals doing their thing and trying to survive. Once people died they were buried in long barrows. These constructions had large stones, megaliths, placed at their entrances. There are a number of these in the Medway area and yesterday I used my exercise to go and complete my total of the East Medway Megaliths. These beasts were placed around 5000 years and and that is pretty darn impressive as far as I am concerned.

Kits Coty

In the past I’ve seen the coffin stone and I’ve also seen Kits Coty before as it’s on a running route I take. Here’s the view from Kits Coty, the weather was lovely but I am concerned that it’s been too warm for too long and the upcoming catastrophe of anthropogenic climate change is accelerating:

I’ve just discovered Scheduled Monuments which is a list of important stuff as agreed by the Secretary Of State for that stuff. There’s a lovely interactive map on the Historic England website. You can also download a PDF version of the map and it is gorgeous. So, Kits Coty is scheduled monument 1012939 and according to that website:

This example has a particularly well-preserved burial chamber and is also of high archaeological potential due to the survival of the remains of the burial mound and the flanking ditches. The burial chamber having been taken into guardianship, the monument is also of high amenity value.
Historic England

Little Kits Coty

Just down the Downs is a collection of stones called Little Kits Coty or the “countless stones”. I think I’ve written about them before but they are still just as pretty and nestled in a corner of a field. There is no path to them so you have to take on the traffic!

These boulders are also a scheduled monument as recognised by the Secretary Of State. These are number 1013673 and part of their description reads:

The atypical example of Little Kit’s Coty House represents an unusual variant of this class of monument but nevertheless forms part of the group of Neolithic burial monuments known as the Medway Megaliths. Being held in Guardianship, the monument is of high amenity value.
Historic England

The White Horse Stone

A small distance away is the White Horse Stone. It’s a single megalith but not quite as mega as the others in this area. According to Wikipedia there were other constructions here but they were destroyed in the 19th century.

This is monument number 1005181 and according to Historic England, again:

The White Horse Stone is a good example of its type, which survives well. The area immediately surrounding the stone is likely to contain archaeological and environmental information relating to the stone and the landscape in which it was erected.
Historic England

I would encourage you to look over the Historic England website as the maps, provided by OS, are absolutely gorgeous and the information there is pretty good. It also has listed buildings on the site and these are indicated on the map with little triangles.

Roman Villa, Eccles

Just south-west of my house lie buried remains of a Roman villa. It was in position from 65CE through to around 400CE which is pretty impressive. While it lies under farmland now it was excavated in the 1960s and it was quite an impressive size. Given how close it is to the site of the Battle Of Medway along with ease of access to the river and lying not far from where the Romans invaded it would have had prominent visitors and been of some importance. It is scheduled monument 1011770 and there are details if you follow that link. Wikipedia has improved over the last few years and there’s quite a bit of information there along with links to the original papers.

The walking route that is safest to travel from Little Kits Coty to the White Horse Stone involves using and underpass to get to the other side of the A229 Bluebell Hill dual carriage way. This underpass is quite pretty in shape and looks exactly like the launch tubes from Battlestar Galactica [imo].

Testing

Along with my investigation of the SARS-COV 2 Virus and how it infects humans I also need to understand how the current detection tests work. Let’s get a few things straight first though. The current [early May] testing regime in the UK is pathetic and nowhere near enough to be able to track where this virus is going. Also, let’s be clear about this, Covid-19 is not a mild cold or flu. Some people won’t suffer very much with it but others are dying. I read a tweet from a 30-ish year old person saying that it felt like they couldn’t breathe for three days. I don’t want to experience that.

There are two main types of test that can be done for the virus. At the moment, in the UK these are done when you first show symptoms. That way, if you have CV-19 you can isolate and if you haven’t then you can go about your business. This is a method for reducing the transmission of this killer disease.

The first test detects the virus itself. This can be done by taking material from easy to reach places on the human body. For this test to work you need to have been infected for a few days already and for the virus to multiply in your body to get to the nose or throat. As the infection continues this test becomes less effective because the virus stays largely in the lungs and reduces elsewhere. As this virus is RNA only and the test can only detect DNA there is some chemistry magic to be done first to convert the RNA and then all DNA in the sample is copied. Finally more chemistry is done to detect the DNA version of the RNA of the virus. This can take two hours to two days. All it tests if whether you have the virus in your nose or throat at that time. It doesn’t mean you are clear. There can be errors.

The second type of test detects the body’s response to the infection. It detects the cells in our blood that fight the virus. By definition this test needs to be done once the infection is being fought. There are two main types of antibody that can be detected and the amounts of those in the blood vary over time. I found this lovely graphic on Wikipedia:

It’s quite hard in these times to find decent correct information on the web about what is going on. I’ve been avoiding newspapers and other traditional media and mainly sticking with podcasts where the presenter / interviewee is qualified or Wikipedia. The World Health Organisation website is brilliant too and has the level of detail I wanted.

My next communication might be about the UK Govt response to this crisis. But I’m not sure I’m willing to enter that pit of desperation yet.

Pass It On

I decided last night it would be sensible to see what facts I can find out about this coronavirus that is spreading around the world. There are rumours of a relaxing of the lockdown and so finally I should learn what I can about the disease. Trying to find reliable sources might be tricky but I’ll spend around an hour and see what I can get.

Transmission Type

Data from published epidemiology and virologic studies provide evidence that COVID-19 is primarily transmitted from symptomatic people to others who are in close contact through respiratory droplets, by direct contact with infected persons, or by contact with contaminated objects and surfaces.

Incubation Period

It would appear that from first contact with the virus it takes a median of 5.1 days for symptoms to show. This means 50% of people will have symptoms before or by five days after infection and the other 50% after 5.1 days. Most people will show symptoms within the first 11 days of transmission. By most I mean around 97%.

Contagiousness

During the incubation period, also known as the “presymptomatic” period, some infected persons can be contagious. Therefore, transmission from a pre-symptomatic case can occur before symptom onset. It is possible that people infected with COVID-19 could transmit the virus before significant symptoms develop. It is important to recognise that pre-symptomatic transmission still requires the virus to be spread via infectious droplets or through touching contaminated surfaces.

A Harvard document has “reports” of people being infectious two days before symptoms start. This is not good and a reason for social distancing. LINK.

Asymptomatic Transmission

An asymptomatic laboratory-confirmed case is a person infected with COVID-19 who does not develop symptoms. Asymptomatic transmission refers to transmission of the virus from a person, who does not develop symptoms. There are few reports of laboratory confirmed cases who are truly asymptomatic, and to date, there has been no documented asymptomatic transmission. This does not exclude the possibility that it may occur. Asymptomatic cases have been reported as part of contact tracing efforts in some countries.

Testing

My current understanding is that testing for Covid-19 requires there to be virus in saliva and or snot. This means that you are likely to be showing symptoms as the virus has replicated enough in your body to affect your mucus membranes. So, if you get a test and it is negative there are some issues. Firstly, false negatives are possible and so the test might say NO but actually you have the disease. Also, you might not have enough of the virus yet so still have the disease but test negative. A positive test is more likely correct although there will be a false positive rate, this is likely much lower than the false-negative rate.

This is quite interesting because one of my standard lessons to Year 11 and also the sixth form is about this exact thing. Is a medical test good enough for use with the public looking at type 1 and type 2 errors.

Source Of Information

All of this information came from World Health Organisation reports from their excellent pages covering this disease.

I feel a little happier now that I have a good source for these facts and feel more confident that I know what I’m talking about. For me one of the saddest aspects of this is the fact that the WHO have to have a page dedicated to myths that are circulating the internet and discussions because largely people can be stupid. It doesn’t help that the US President is a fucking lying racist sexist moron and other leaders around the world are also stupid [Brazil and UK, also many more].

When this is over I hope there’s a bonfire of those leaders who did nothing for the two or three weeks when it was clear that Italy was fucked. It seemed obvious to me at that moment that we needed to shut the country down to save lives. It was ridiculous that I was expected to work in an environment of around 1500 people many of whom had returned from skiing holidays or similar. I just don’t think the leaders of many countries understand the following:

Exponential growth
Six degrees of separation
Combinatorics
Vectors of disease transmission
How to be nice and do the best you can for humanity

LLAP.

Purge Problems – Fixed

Recently I had to fix this site as some malicious code had appeared in the file structure and, although the site looked OK to me I know it was sending some observers off to obscure sites. So, having had this happen once before about four years ago I had a good sense of what needed to be done and also what the dodgy php files looked like.

So, I set off to purge the website of anything that looked a little dodgy. Then using what remained and back ups from before I was able to rebuild the site and get it running as it was, minus one communication that was titled “Well” but while I probably moaned about CV-19 and said some stuff that I’m doing I don’t know what it was about. I had a look at the WayBack machine but it hadn’t crawled my site that recently.

It also turned out that I deleted an index file of one of my old websites in the purge. I guess it was easy to do. The problem was that now I didn’t have a copy of that file and I couldn’t even remember what style it was or what it looked like. I had moved away from FTP back ups and more to using some backup plugin to my site. This was a mistake. I had thought that this page might be lost forever and then I remembered the WayBack machine.

My first search was for the page on this site. Nothing was retrieved and then I remembered that the Internet Archive might have got a snapshot of my original site. It had! With some tweaking of the HTML code I was able to recreate the index page and now this site runs 99.99% the same as it did before I got fucked over. I’ve also been trying to think of all the domains I have owned in the past and I think this list is about all of them:

iparish.org.uk
ianparish.me.uk
iparish.plus.com [not really owned by me as it was a sub-domain]
whatuseismaths.com
fooyah.net/wordpress

I think that’s it. I’ll chuck in another if I think I’ve missed one. I’m struggling to know how I used to edit my webpages because I don’t recall having a computer before around 2001 but maybe I did. Internet access was poor then anyway. I do know that when I worked at my second school in about 1998 I had a site that was up and running.

My OldSites are listed on this page.

Set Up

I spent part of yesterday setting up the final parts of the new PC. I’m very happy with the result. The new things are the PC itself and some peripherals like the keyboard, mouse and mat. Because the mousemat thing was too big for the old desk I bought a new desk for the PC. I was stuck with the sizes that the desk could be because of the tiny size of my dining room which is where it all lives. I guess I could have put the system somewhere else but I wanted this position for the easy access to a wired LAN.

I guess apart from tidying up cables I am done. It was very satisfying to wire in the whole system in its home for the next few years.

Green

Yesterday while out for my allowance of daily exercise I noticed how lovely and green everywhere was looking. The sun and warmth over the last month – not a good thing by the way – has really helped the flora develop. Every path I walked on seemed lush and vert. Here’s a photograph I took while at one of the river Medway inlets, the old brickworks wharf.

Here’s a very nondescript satellite view of where the photograph was taken.

Clouds

It’s a funny old thing that when flying in X-Plane you wish for clouds but they kill your frame rate because it’s X-Plane. Then when you finally put clouds in or real time weather you end up with not being able to see anything most of the time because – clouds. You have to take off in cloud or fly through cloud and then not see anything for a while. Once above clouds the world looks pretty much the same wherever you are.

Look at this picture. It’s gorgeous but the world looks faded because it’s not that often you get the wonderful clear days where you can see for miles.

Habits

Considering how much time at home I have at the moment you would think that I would be writing quite a lot on this site. I think I’ve just got out of the habit and the next album review is going to take some time so this is a communication make me feel as though I’ve actually done something positive. I’ve spent quite a bit of time sorting out the technology in the house over the last few weeks.

I have bought and installed a new PC including getting the software all transferred and working properly. I’ll put some pictures on here once it is finally complete. I’m waiting for some kit to arrive and I need to get out to collect the new desk for it. After that I’m sure I’ll put something on here about it. The new PC runs X-Plane a lot better than the old one so I’ve been playing on that a little recently.

I’ve been playing some Minecraft running my own server. It’s good fun and feels productive. I really enjoy the farming and mining aspect of this. The complex builds I leave to the kids. It’s a far better world than this one currently. To enable three of us to play in the house we are using the Bedrock edition along with playing on the PS4, PC and iPhone. The phone has a DS4 controller binded to it and then the video is output to the TV in the dining room. This whole system works quite well but when moving from one platform to another some of the button mapping is slightly different and this can cause issues.

I’ve also been playing Deliver Us The Moon on the PS4. I’m enjoying it. The puzzle solving isn’t that hard but there have been times I’ve wandered around trying to figure out what I am meant to do. I hope to finish this game over the next week or so.

Next week I’m going to get back to writing “music” on the PC. I’ve been practising recently trying to re-learn the things I last did about five years ago. I’ve also changed which software I use to one that seems a little more intuitive. Eventually I hope to write something that actually sounds good and fun. It’s hard because I nearly gave up at first before I remembered that everything is hard at first and the only way to get better at something is to do that thing. It’s something I say in my day job a lot and it’s nice to take my own advice!

I installed some security cameras in the house. Not really because I’m worried about crime but more because I can and they were on sale on Amazon. I do like that they alert me when there is movement in the frame and they also have a good night mode. What I’m less happy about is the auto-arming software needs to always run on my phone and I don’t like any piece of software that does that. This isn’t a problem at the moment because it’s not like I’m leaving the house that much. I’ll investigate more when I return to work.

I am working. From home. In a way that seems strange but I’m doing what I can and trying my best given the resources and limits that I have. I do hope everyone is safe and that’s the bigger issues really. I know I’m lucky to still be getting paid and I am making sure that is justified. I wish everyone well at the moment and understand that I come from a position of privilege completely on this. This current lockdown situation must be utter shit for a lot of people. I’m reasonably used to being away from work for the summer holidays and I have been thinking that the last summer I worked through was probably when I was nineteen in 1991. I have only ever had one job where the summer was just a normal work time.

I’ve been listening to podcasts while moving around the house and doing little things. I would normally have the radio on and listen to a radio station from New Orleans but their news is just as shit as ours and so now I’m trying to listen to more podcasts and that means just playing stuff through my phone during the day. Mind you, I can only concentrate on the podcast when I have certain brain functions going. While typing this I am listening to music, because I am doing words and so listening to conversation would confuse me more than I am currently. I’m listening to Amerikkkant by Ministry.

On to the habits. I need to change my habits slightly to make sure I add content to this site whenever possible. I’ve been away for a little while and I’ve been busy restoring this site along with setting up things on a new PC. Also, I’ve been trying to make sure that my back up systems work properly. There are routine things that I am working on to improve my site security and content. Here’s to new habits and enjoying the things we do along with being productive.

Red Hawk

This is my first communication on this restored site. I can’t see anything wrong with it at the moment although I may have deleted one of my old websites and I think that has gone forever. I’m sure one of the spare hard drives knocking around will have a copy but it’s whether I can be bothered to go and look for it. There’s a time/reward concept I’m trying to develop and the ratio is pretty low for that one.

Since 17th March 2020 I have spent just one day in work and that was voluntary. I helped supervise those children of keyworkers on Monday and it was nice to be somewhere else. While I feel OK 80% of the time I’m sure a change in scenery helped me for a few days. It’s been over a week since I was last feeling rather desperate. The big news, buried in this paragraph, is that the lockdown is costing me quite a bit in terms of technology that I keep buying. I think I’m done for now, but the most recent purchase was a new PC. I had a situation with the old one and although I think that was largely my fault – I was removing a headphone jack when it powered down – the headphone jack is close to the power button and I think it activated it -the PC was old and I decided that a new purchase would last a good five or six years and need to be quite good for gaming.

So, the PC has 16GB ram, an Intel Core i5 and a RTX 2070 graphics card. So far I have been very impressed although I’ve also upgraded some of the infrastructure surrounding the PC to suit the new machine. Setting up the PC was straight forward and installing all the relevant software that I wanted was easy and took about a day. A bonus of getting a new PC is the ability to break the old one down and use its components. So, the old SSD is now installed on the PS4 as extra storage space and that works well. I bought a cheap enclosure for the SSD and now have an extra 500GB storage on that. I had a back up hard drive running in the old PC also and that has found its way into the new machine and still runs as a back up to the NAS.

The most important bonus of this new machine is that it runs X-Plane quite well. There is no stuttering under high graphics settings and while I’m not fussed about super realistic VFR graphics, the whole simulator runs really well. I have bought some aircraft in the past, most notably an F18, F35B and a V-22. I wanted something a little simpler to fly but also fast. There are quite a few prop planes included in X-Plane but they don’t fly that fast and what you want to do when playing is get up quick, do some aero, shoot some stuff down and then get somewhere else quick.

I had a look at AOA Simulations as they are people I have bought from before and they had an advanced trainer jet for sale. It’s the T-7A Red Hawk. It’s a nice looking plane and so I paid for it. Some of the freeware on X-Plane is pretty good but the level of detail on the payware is delightful. I’m aiming to upload some videos of this beauty to YouTube and will do so once i figure it out. But, screenshots are easy and here are some I’ve taken.

Someday soon I’ll give more details and links to lovely stuff as I explore this aircraft and X-Plane a little more. Just as a guide I used to get around 15-20 FPS on my old PC and the bottleneck was the processor. On this current/new machine I’m getting 50-60 FPS. Now, to you ultra-gamers out there 50-60 might not seem like much but I have to tell you that X-Plane is a stupid simulator and anything more than 30 is a decent job. Have a look at the forums and see people complain about clouds and almost everything getting in the way of frame rates above 20. Anyway, I’ve got places to fly.
